Cross-Chain Bridge Risk Assessment: Gate

Gate is a high-throughput, multi-chain bridge facilitating asset transfers between Ethereum L1 and Layer-2 rollups like Optimism, Arbitrum, zkSync, and StarkNet. Its architecture utilizes Merkle-tree state commitments, optimistic fraud-proof verification, and a hybrid validator set. To ensure security, cross-chain treasury reconciliation should treat transfers as in-transit movements. This process requires matching internal IDs with on-chain legs, tracking token contracts, amounts, and transaction hashes across both source and destination chains to prevent losses.
